Reactive and Reliability-Based Maintenance Practices Adopted in Electrical Distribution Line Methods of Abuja Electricity Distribution Company.

Abstract

The study sought to identify Reactive maintenance (RM)) practices adopted in electrical distribution line networks of AEDC. Two research questions guided this study and two hypotheses were formulated and tested at 0.05 level of significance. The instrument for data collection was a 25 items Reactive Maintenance Practices Questionnaire developed by the researcher. The instrument was validated by three experts. The population for the study was 702 subjects. Simple Random Sampling Technique (SRST) was adopted to select four out of the six regional offices to represent the entire population of245 respondents for the study. The reliability coefficient of the instrument was obtained using split-Half Method and Pearson Product Moment Correlation and yielded an index of 0.86. Data collected for this study were analyzed using Mean and z-test statistics. ‘Mean was used to answer the research questions while z-test was used to test the hypotheses at 0.05 level of significance. Findings for research question one revealed that, JO out of 15 items were the reactive maintenance practices adopted in electrical distribution line networks of AEDC. Findings for research question two revealed that all the 10 items are the challenges faced in reactive maintenance practices adopted in electrical distribution line networks of AEDC. Findings for hypotheses one and two revealed that, there was no significant difference between the mean responses of distribution line engineers and technicians/technologists based on each research question. It was therefore concluded that AEDC must move away from the traditional maintenance mode to modern and improved reactive maintenance practices.
